Utilizing saline soil and water resources are essential in meeting future demands for food, feed, and biofuels in a world of increasing freshwater scarcity, by use of halophytes (salt-loving plants). The succulent halophyte Salicornia bigelovii Tor. was cultivated as a green biomass crop irrigated with saline aquaculture effluents, and bio-fractionation was tested as a way to improve the value of the crop. Bio-fractionation proved to be an effective way of extracting ash and nitrogen into the green juice fraction, from which a protein concentrate was produced with 15 % crude protein and 33 % ash. The fiber fraction was not found useful as fodder due to a relatively low crude protein content of 4.1 % and 10–12 % remaining ash. However, the high digestibility of the structural carbohydrates in the fiber demonstrated its potential as a feedstock for biorefining with estimated bioethanol yields around 2500 L/ha.

通过生物精制增加在沙漠环境中生长的拟南芥绿色生物量的价值

在盐分稀缺的世界,通过使用盐生植物(喜欢食盐的植物),利用盐碱土和水资源对于满足未来对食物,饲料和生物燃料的需求至关重要。肉质盐生植物大叶Tor。将其作为灌溉有盐水养殖废水的绿色生物质农作物进行种植,并测试了生物分离技术以提高农作物的价值。事实证明,生物分离是将灰分和氮提取到绿色汁液馏分中的有效方法,从中可以生产出15%的粗蛋白和33%的灰分的浓缩蛋白。由于相对较低的粗蛋白含量为4.1%,且剩余灰分为10-12%,因此未发现纤维部分可用作饲料。但是,纤维中结构性碳水化合物的高消化率表明其作为生物精炼原料的潜力,估计生物乙醇产量约为2500 L / ha。
